The place I work part time has these in the cabinets. Now I'm not saying to go out and buy a $350 setup like that but it's merely a computer fan and a humidity controller with a bucket. The things I see people do on here would make this thing a no brainer. The humistat could be adjusted up fairly high to the point it will seriously over humidify cigars. So it should be perfect for keeping 80-90% in a closed cabinet setup. If someone added a small warmer to the water tank it'd be even easier. It's pretty basic the fan pulles air in from the top across the water and through a wick which is made of chamois. Use distilled and you're fine.
Also this is a great website I've been checking out. http://curedmeats.blogspot.com/
It may have been listed already somewhere but if not, enjoy!
